Turkey's Foreign Ministry says it has summoned the Russian ambassador in Ankara to complain about protests against Turkish missions and businesses in Russia following Turkey's downing of a Russian jet.

The ministry said in a statement on November 26 that it wanted to express Turkey's discontent over the "unacceptable" incident as well as over a series of incidents against Turkish companies in Russia.

The statement said Turkish offices had come under what it called physical attacks disguised as protests, and warned Russian authorities to urgently increase protection for the embassy and other Turkish interests.

Protesters in Moscow hurled eggs and stones at the Turkish Embassy on November 25, breaking windows in the compound.

Police cleared the area and made some arrests shortly after the protest began.
